A man in his fifties drowned yesterday afternoon while fishing for salmon on the River Moy close to Foxford.
His body was recovered later and brought to Mayo University Hospital in Castlebar where a post mortem will be carried out today.
Other anglers in the area were unable to save the fisherman who apparently lost his footing.
The tragedy occurred close to Foxford Bridge.
Gardai are withholding the name of the victim until relatives have been notified.
